  104. * IS INVOKED AUTOMATICALLY TO LOG IN A USER'S FILES 00098000
  105. * FROM HIS A-DISK. IF A PROFILE EXEC EXISTS IN THE 00099000

  111. * PROFILE EXEC. 00105000
  112. * 00106000
  113. * IF AN ACCESS IS ISSUED AT A LATER TIME, FOR ANY DISK, 00107000

  202. * ALL FILES. ERASE OR EQUIVALENT IS VALID ONLY 00187000
  203. * FOR A READ-WRITE DISK, AND THE 'CUU' MUST BE 00188000
  204. * SPECIFIED. IF BOTH CONDITIONS DO NOT EXIST, 00189000
  205. * ERASE IS CONSIDERED AS AN INVALID 00190000

  213. * BUT THE COMPUTED VALUE MUST BE NONZERO AND LESS THAN 00198000
  214. * X'FFF'. IF PROVIDED AND LEGITIMATE, ITS VALUE IS 00199000
  215. * USED IN PLACE OF THE DEFAULT DISK-ADDRESS (I.E., 191) 00200000
  216. * IN THE DEVICE TABLE. 00201000
  217. * 00202000

  229. * INDICATING THAT THIS WILL OCCUR IS TYPED. 00214000
  230. * 00215000
  231. * 00216000
  232. * 1. DMSALU IS CALLED TO CLEAR 00217000

  234. * TABLE. 00219000
  235. * 00220000
  236. * 2. THEN DMSACM IS CALLED TO 00221000
  237. * BRING IN ALL PERTINENT INFORMATION ON THE DISK 00222000
  238. * EXCEPT THE FST HYPERBLOCKS CONTAINING THE FST 00223000

  240. * IN IF DMSACF HAD BEEN CALLED). 00225000
  241. * 00226000
  242. * 3. IF AN ERROR IS RETURNED BY DMSACM 00227000
  243. * IT IS RETURNED TO THE CALLER WITH THE ERROR 00228000
  244. * PROPER ERROR CODE. NOTE THAT IF THE DISK IS 00229000
  245. * READ-ONLY, THIS IS TREATED AS AN ERROR CONDITION. 00230000
  246. * 00231000
  247. * 4. UPON SUCCESSFUL RETURN FROM DMSACM, IF THE DISK 00232100
  248. * IS AN O/S DISK, CONTROL IS RETURNED TO THE CALLER, 00232200

  254. * 00237000
  255. * 5. THE QMSK BROUGHT IN BY DMSACM 00238000
  256. * IS NOW CLEARED, AND THE APPROPRIATE DISK COUNTS 00239000
  257. * RECOMPUTED AND STORED TO REFLECT A CLEAN DISK. 00240000
  258. * 00241000
  259. * THE QQMSK BROUGHT IN BY DMSACM IS ALSO CLEARED. 00242000
  260. * 00243000
  261. * CAUTION: ACCESS WITH THE ERASE OPTION SHOULD ONLY BE USED 00244000
  262. * WHEN ALL OLD FILES ON A DISK (IF ANY) ARE TO BE 00245000
  263. * DISCARDED. IT IS EQIVALENT, IN EFFECT, TO FORMAT'ING 00246000
  264. * THE DISK, OR ERASING ALL FILES THEREON, BUT IS MUCH 00247000
  265. * FASTER AND MORE EFFICIENT. NOTE, HOWEVER, THAT IF A 00248000
  266. * USER ISSUES THIS OPTION BY MISTAKE, THE FILE 00249000
  267. * DIRECTORY ON THE GIVEN DISK HAS PURPOSELY NOT BEEN 00250000
  268. * UPDATED BY DMSACC (NO CALL TO DMSAUD IS MADE); 00251000
  269. * AND THEREFORE THE USER CAN RECOVER HIS FILES BY 00252000
  270. * IMMEDIATELY ISSUING AN ACCESS COMMAND FOR THE DISK 00253000
  271. * WITHOUT THE ERASE OPTION. 00254000

  273. * NOTES: 00256000

  275. * 1. IF ANY DISK IS LOGGED IN AS A CMS R/O DISK, FOR 00258100
  276. * WHATEVER REASON, ONLY FILES HAVING A MODE-NUMBER 00259000
  277. * OF 1-6 ARE ACCESSED. FOR A READ-WRITE DISK, ALL 00260000
  278. * FILES ARE ACCESSIBLE, FROM MODE NUMBERS 0-6. 00261000
  279. * THEREFORE, 0 FILES ON ANY DISK CAN BE CONSIDERED 00262000
  280. * "PRIVATE" TO THE USER WHO HAS READ-WRITE ACCESS TO 00263000
  281. * THE DISK, AND NO ONE HAVING READ-ONLY ACCESS TO 00264000
  282. * THE DISK CAN REFERENCE THEM. 00265000
  283. * 00266000
  284. * 2. IF THE FIRST USER COMMAND IS ACCESS, THEN DMSINT 00267000
  285. * AND DMSACC (WHICH WORK TOGETHER ON THE FIRST COMMAND 00268000
  286. * ISSUED AT THE TERMINAL) ACCEPT THAT FIRST COMMAND AS IS, 00269000
  287. * AND DO NOT ISSUE ANY IMPLIED AUTOMATIC ACCESS OF 00270000
  288. * THE USER'S NORMAL A-DISK (191). THEREFORE, IF THE 00271000
  289. * USER WISHES TO ACCESS HIS A-DISK AND THEN 00272000
  290. * IMMEDIATELY ACCESS ANOTHER DISK IN ADDITION, HE 00273000
  291. * SHOULD ISSUE A SPECIFIC ACCESS COMMAND FOR HIS 00274000
  292. * A-DISK FIRST, AND THEN THE OTHER COMMAND. 00275000
  293. * 00276000
  294. * IF THE USER DOES NOT WISH TO ACCESS ANY USER DISKS 00277000
